How much of that can be accomplished these days with Photoshop? Do you still think shooting with a filter is as essential as it was in the pre-computer age?

I need to take a class somewhere.

A lot can be accomplished with Photoshop, but you are always limited by the information captured by the camera. After the Maze trip where I used a borrowed polarizing filter, I'll always use one outside.

As far as a class, I have a professional photographer friend (find Michael McConnell through my FB page) who keeps threatening to do a class. He's mildly into wheeling too and maybe we can corral him for a day. Another friend, Dmitry, who some of you met on the Spooky Night Run is also way into it and I learn a lot from him.
